I don't know...
What the facination is ...
About all the Washers and Dryers in a row ??? To me it's sort of a "Power, Strength, and Satifaction " Thing. But most of us now have that in our Own Spaces.
For example, I have 2 KitchenAids running. The 806, and a HOH Dryer. It's almost better than having a boyfriend LOL, They all don't talk back, let alone when they break down, there is nothing to do but fix it. LOL
